Patented Dec. 23, 1941 UNH' STATES PATENT OFFICE This invention relates to storm window structures for inside use, and the main object is to provide a metal combination storm window and screen assembly for inside installation and for winter and summer use. Another object is to provide a structure of the kind referred to in a simple, compact and efficient form, comprising a metal frame adapted to fit within the window frame, from which the inside stops, beading or strips have been removed and replaced by special strips for engaging a sponge rubber beading to contact the frame, the frame being divided into upper and lower sections by a parting strip, and

a pair of specially constructed metal sash mounted in the frame with the panes thereof also rubber-sealed at their margins.

With the foregoing objects inview a preferred embodiment of the invention is shown in the accompanying drawings, wherein:

Figure l is an inside elevation of the assembly constituting the elements of the invention, as mounted within a conventional window frame.

Figure 2 is a cross-section on the line 2-2 of Figure l.

Figure 3 is an enlarged sectional detail of the base parts of the assembly.

Figure 4 is an enlarged detail showing a method of anchoring, the assembly within the window frame.

The frame and sash combination comprising the subject matter of the invention, is designed for application to a conventional window A having a frame 13 and including the inside facins strips C, from which the usual inner beading or stop-strips (not here shown) have been removed.

The invention comprises a special stop-frame It made of wood or metal strips and being on a cross-section of the form of an inverted L, with webs 5a. and 5b defining a right-angled notch or groove 6. This frame is permanently mounted within the facing strips C of the window frame,

- in place of the removed stop strips. The frame 5 is constructed with the angular groove 0 facing inwardly, or towards the inner side of the window as shown, and channelled beading or lining I of soft rubber or the like, is seated along within the groove 8 all around the frame I.

an inner metal storm frame I is then provided, adapted to fit within the'facing strips C,

at the inner side of the window frame. This frame includes sidestrips 0a, a top strip 8b, a bottom strip 90 and a medial cross strip Id. All of the outer or marginal strips comprising the frame are angular or L shaped in cross-section and include webs 0e extended perpendicularly towards the groove 0 of the frame I. themargins of these webs being rolled to form beads If for forcing into the channels la of the rubber linings 1, thus providing tight Joints all around the frame 9. The inner margins of the upper and lower openings of the frame 9, are rolled out towards the frame 5, as shown at ill to form channels Ilia for receiving rubber beads or sealing strips 1 i. The free margins or edges of the rolls III are turned back again towards the plane of. the frame 9', that is to say towards the common plane of the strips or webs 9a, 9b, 9c, but

fall so far short of this plane as to provide a slight space i8, permitting the insertion of glass panes l2 within the openings of the frame, in the plane of thestrips 9a, 9b, 9c, with the panes having abearing back against the sealing beads II. The panes being thus mounted,- metal facing strips i3 are mounted around the margins of the frame openings, the same overlapping the upper glass pane and being secured in place by means of short set-screws l4 passedv through the strips into the webs of the frame 9. Thus an absolutely tight closure is provided at the inner side of the window, and the inclosed inner air space between the regular window and this storm window or assembly, provides effectual insulation against outer temperature changes.

If desired the lower pane of glass It may be set in a separate frame ill, and this frame then hinged at IE to the main frame 8, whereby the hinged frame may be opened as desired for ventilation, or for summer use. Or for summer use a screen (not shown) may be substitutedin' the frame I5.

The frame 8 may be locked within the window frame by means of lugs il secured to the window frame.

From the foregoing description the construction and use of the invention will be readily understood, and while I have here shown and described certain structural features of the invention, the same may be changed or modified within the scope of the claim.

I claim:

In a structure of the kind described, a removable storm-frame for fixed positioning inside a window-frame inwardly of a stop-frame, the

rails of the storm-frame being right-angled in cross section. with one web of each rail having a free edgedirected centrally in'the plane of the
